Thorgal leaves on the ground to try to reach a vicken village when suddenly he is blocked in the mountain by an avalanche which obliges him to take refuge in the ruins of an old house. He meets there the young Torric who came to hide after having fled from the claws of the terrible Saxonygaard, the master of the mountains who terrorizes the peasants around. The next day, as the young man tries to escape again, he finds himself, suddenly, with Thorgal in the middle of a spring landscape, the snow disappeared and in front of them this, at the door of the miraculously rebuilt house, the beautiful Viana who threatens them with his crossbow. Thorgal wonders what this leap in time means!
